METHOD FOR PRODUCING COMPOSITE OF CFRP WITH METAL MATERIAL AND COMPOSITE THEREOF

A CFRP material with an Al alloy sheet attached to or a CFRTP material with an Al alloy sheet attached to is prepared by joining an Al alloy sheet with a CFRP material or a CFRTP material by adhesion or by injection molding. The surface of this Al alloy sheet and a surface of metal material such as Ti, etc., are subjected to chemical treatment. After this chemical treatment, the CFRP material with an Al alloy sheet attached to or the CFRTP material with an Al alloy sheet attached to and the metal material are inserted into a metallic mold for injection molding so as to have a gap therebetween. High crystalline thermoplastic resin is injected into this gap to join the metal material with the Al alloy sheet, thus obtaining a laminated composite.

Transferring nanofiber forests between substrates
11613468 · 2023-03-28 · ·

Techniques are described for transferring nanofiber forests using transfer films that either lack a conventional adhesive at the substrate-nanofiber forest interface or that include a diffusion barrier that prevents diffusion of adhesive molecules (or other polymer molecules mobile at ambient temperatures) into the nanofiber forest. These techniques can be applied to single layer nanofiber forests or stacks of multiple nanofiber forest. By selecting the bond strength between the nanofiber forest and the transfer films, the nanofibers can be aligned in a common direction that includes, but is not limited to, perpendicular to a substrate or transfer film.

Laminate sheet

An object is to provide a coloring technique that makes it possible to impart luster while providing a vivid color, and further to provide a coloring technique that makes it possible to retain more unevenness when a substrate has unevenness. This object is achieved by a laminated sheet comprising a fiber substrate and a metalloid element-containing layer disposed on or above the surface of the fiber substrate.

Cross layer fiber entanglement to increase strength of 3D part
11485110 · 2022-11-01 · ·

A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.
